What is a Bruker OPUS file?

OPUS is the native spectrum format of Bruker FTIR and Raman instruments, saved with numeric extensions like .0, .1, .2 (and .opus). The data is binary and normally only opens in Bruker's OPUS software on the instrument PC. This page reads the file in your browser and plots it - so you can view or share a spectrum without OPUS installed.
